z'claims, (o1; 16-149) The present invention relates to new and usefulimprovements in hinge construction foreasily and quickly mounting ascreen door, movable partition, or the like, in position on a frame, orjamb, and the invention has for its primary object to provide fasteningmeans for securing the hinge to the door frame without necessitating theremoval and replacement of screws or other fastening devices each timethe screen door is hung.

A further object is to provide a device of this character of simple andpractical construction, which is neat and attractive in appearance,

strong and durable, relatively inexpensive to manufacture and otherwisewell adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which Figure 1 is afragmentary elevational View of a screen door showing the hinge inposition for at taching the same to the door frame,

Figure 2 is a sectional view taken substantially on a line 2-2 of Figure1,

Figure 3 is a fragmentary group sectional view showing the hinge platein position for placing over the permanently attached fastening screws,

Figure 4 is a plan View showing the locking plate in its releasedposition,

Figure 5 is a perspective view of the locking plate,

Figure 6 is a similar view of the permanent anchoring plate,

Figure 7 is a plan view showing a modified form of locking plate,

Figure 8 is a fragmentary side elevational View of a door jamb showing amodified form of hinge fastener, and

Figure 9 is a sectional view taken on a line 99 of Figure 8.

Referring now to the drawings in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the numeral 5 designates the door frame while the numeral 6 designatesthe frame of a screen door. The hinge is designated generally at I andincludes the hinge plate 8 which is secured to the screen frame 6 bymeans of screws or the like 9.

A permanent fastening plate I is secured to the frame adjacent its edge,the plate Ill having openings II formed adjacent each end for receivingscrews or the like (not shown) for permanently securing the plate I!) tothe frame 5.

Rising from the plate I0 is a plurality of apertured bosses I2 throughwhich fastening screws I3 are inserted, the heads M of said screws beingspaced outwardly from the bosses as shown in Figure 3 of the drawings.

The other hinge plate of the hinge, is designated at I5 and is providedwith openings I6 of sufficient diameter to receive the heads I4 and thebosses I2 so that the plate I5 will rest flatwise against the plate Ill,and the bosses I2 snugly engage in the openings I6. The bosses I2 areconstructed of a depth corresponding to the thickness of the plate I5 sothat the edges of the bosses are flush with the surface of the plate I5,and the heads I4 of these screws I3 will thus project above the surfaceof the plate I5.

A locking plate I1 is slidably mounted on the plate I5, the lockingplate I I being positioned between the upstanding fianges I8 formed atthe opposite ends of the hinge plate I5 and said 7 flanges adjacent theouter edges of the plate I5 are formed with inwardly projecting stops I9adapted for engagement by lugs20 formed on the inner edges of thelocking plate II. In the form of the invention illustrated in Figures 1to 6 inclusive, the locking plate I1 is adapted for horizontal slidingmovement, the lugs 20 preventing complete removal of the locking platefrom the hinge.

The inner edge of the locking plate I1 is formed with slots 2| adaptedfor receiving the shanks of the screws I3 so that the locking plate mayslide under the heads I4 of said screws whereby to anchor the plate I5against movement on the fixed plate I0.

In the form of the invention illustrated in Figure 7 of the drawings,the locking plate is designated at 22 and is adapted for slidingvertically on the hinge plate I5 through openings 23 formed in theflanges I8 of the hinge. The locking plate 22 is formed with keyholeopenings 24 for receiving the screws I3 and sliding under the heads I4of said screws to secure the hinge in position. The plate 22 is alsoprovided with vertically extending slots 25 through which headed screws26 are inserted and attached to the plate form of fastening means forthe hinge plate IS, the permanent plate It) being dispensed with and aplurality of tubular members 21 are sharpened at one end as shown at 28and driven into the jamb 5. The outer end of the tubular members projectbeyond the surface of the jamb a distance equal to the thickness of theplate l5 through the openings of which the tubular members are insertedso that the ends of the members will be flush with the surface of theplate.

The screws 13 are threaded into the members 21, or the screws may be ofsufficient length to be freely inserted in the members and threaded intothe jamb, the heads of the screws projecting beyond the plate I5 toreceive the locking plate as heretofore explained.

It is believed the details of construction and manner of use of thedevice will be readily understood from the foregoing without furtherdetailed explanation.

What I claim is:

1. A hinge comprising a pair of hingedly connected plates adapted forattaching respectively to a door jamb and to a door for swingablymounting the door on the jamb, a plate permanently secured to the jambunder the adjacent hinge plate and having outwardly projecting aperturedbosses projecting through the said adjacent hinge plate, screwspositioned in said bosses and having heads outwardly of the said hingeplate and a locking plate slidably mounted on the hinge plate and havingslots receiving the screws to engage under the heads of the screws forreleasably securing the hinge plate to said permanent plate.

2. A hinge comprising a pair of hingedly connected plates adapted forattaching respectively to a door jamb and to a door for swingablymounting the door on the jamb, a plate permanently secured to the jambunder the adjacent hinge plate and having outwardly projecting aperturedbosses projecting through the said adjacent hinge plate, screwspositioned in said bosses and having heads outwardly of the said hingeplate and a locking plate slidably mounted on the hinge plate and havingslots receiving the screws to engage under theheads of the screws forreleasably securing the hinge plate to said permanent plate, and stopson the hinge plate and on the locking plate engageable upon apredetermined sliding movement to prevent separation of the lockingplate from the hinge plate.
